8 Gauss, High Performance h 3-axis Magnetic Sensor MMC5983MA FEATURES Fully integrated 3-axis magnetic sensor and electronic circuits requiring fewer external components Superior dynamic range and accuracy: 8G FSR 18bits operation 0.4mG total RMS noise Enables heading accuracy of 0.5 Max output data rate of 1000Hz Industrial standard low profile package 3.0mm x 3.0mm x 1.0mm FUNCTIONAL BLOCK DIAGRAM Degaussing with built-in SET/RESET function Eliminates thermal variation induced offset error (Null field output) Clears the residual magnetization resulting It can measure magnetic fields within the full scale from strong external fields range of 8 Gauss (G), with 0.25mG/0.0625mG per On-chip sensitivity compensation LSB resolution at 16bits/18bits operation mode and 0.4 On-chip temperature sensor mG total RMS noise level, enabling heading accuracy Data Ready Interrupt of 0.5 in electronic compass applications. Low power consumption An integrated SET/RESET function provides for the 1A power down current elimination of error due to Null Field output change with 2 I C Slave, FAST(400KHz) mode temperature. Temperature information from the 2 3.0V single low power supply integrated temperature sensor is available over the I C SPI interface available Interface. The SET/RESET function can be performed RoHS compliant for each measurement, periodically, or when the temperature changes by a predetermined amount as APPLICATIONS the specific application requires. In addition, the SET/RESET function clears the sensors Electronic Compass & Navigation of any residual magnetic polarization resulting from Position Sensing exposure to strong external magnets. General Purpose Magnetic Field Measurements The MMC5983MA is packaged in a low profile LGA package and an operating temperature range from - DESCRIPTION 40 C to +105 C. 2 The MMC5983MA is an AEC-Q100 qualified complete The MMC5983MA provides an I C digital output with 3-axis magnetic sensor with on-chip signal processing 400 KHz, fast mode operation, and a 10MHz SPI digital 2 and integrated IC/SPI bus suitable for use in output. automotive applications. The device can be connected directly to a microprocessor, eliminating the need for A/D converters or timing resources.

Supply current is proportional to how many measurements performed per second. 2. Based on 3lots characterization result. 3. MEMSIC product enables users to utilize heading accuracy to be 1.0 degree typical when using MEMSICs proprietary software or algorithm. 4. Sensitivity of the orthogonal axes is analytically derived from raw data and is subsequently processed by MEMSIC software drivers. 5. Based on shipment test result. 6. This is the magnitude of external field that can be tolerated without changing the sensor characteristics. If the disturbing field is exceeded, a SET/RESET operation is required to restore proper sensor operation. MEMSIC MMC5983MA Rev A Page 2 of 20 Formal release date: 4/3/2019
